葡萄糖酸钠不同温度条件下的掺量试验

Experiment of different sodium gluconate dosage under different temperature conditions

本文试验研究了华北地区不同温度条件下葡萄糖酸钠掺量与混凝土凝结时间、混凝土状态、混凝土1 d、3 d、7 d、28 d强度之间的关系,确定华北地区在不同温度条件下葡萄糖酸钠的最大掺量,同时建立葡萄糖酸钠在泵送剂中的掺量与温度之间的公式,以方便实际应用时查询使用。

In this paper,the relationship between sodium gluconate content and concrete setting time,concrete state,concrete strength at 1 d,3 d,7 d and 28 d at ditTerent temperatures in North China was studied experimentally.The maximum dosage of sodium gluconate at different temperatures in North China was determined,and the formula between the dosage of sodium gluconate in pumping agent and temperature was established,which was convenient for inquiry and use in practical application.
